Laser treatment for upper urinary tract

From October 1986 to October 1992, Six patients were evaluated for ureteroscopic treatment in combination with Nd: YAG laser treatment of upper urinary tract tumors. Tow patients had benign ureteral polyps. 4 patients had transitional cell carcinoma. Two Patients with polyp were only treated ureteroscopycaly. 4 carcinoma patients were treated 5 times by laser. One patient had local recurrence and 1 patient had high grade bladder tumors and multiple ureter tumor. Finally both of these patients were treated by nephroureterectomy. Of 5 patients with ureteral tumors who were believed to be candidates for endoscopic therapy, 4 were controlled by this method of treatment. In selected individuals ureteroscopic laser treatment of upper urinary tract transitional cell carcinoma can achieve local control with renal preservation.
